Best Concert I went to (Non Smashing Pumpkins) was surprisingly Kieth Urban at USANA. He put on a really great show and for myself not being a big country fan found myself coming away impressed at his energy and charisma with the audience.
Best Concert Smashing Pumpkins was at in the venue or Saltair....small places, packed to the rims, good times.
I spend way too much on concerts apparently because i started thinking about all the shows i've seen. No Doubt puts on a really good show. Weezer as well. I saw Page & Plant awhile back, really cool to hear the classics from those guys.
Concerts I missed....U2 with Rage would have been fun, Tom Petty, Paul McCartney at Rio Tinto would have been cool.
Concerts I wished I missed....all the country my wife drags me too (in all fairness i drag her to all the BYU games), Sarah Evans, Gary Allen, Toby Kieth, Little Texas, Some guy i never heard of and his amazing band, Kip Moore....but Carrie Underwood was actually pretty good....my days as a security guard for N Sync.
The Ratt/Ted Nugent show was something else and who could forget the Orem Scera Shell presentation of Survivor! It was awesome! they played one song and left because of rain. and we all waited and waited and waited hoping to hear eye of the tiger.
